_nc_freeall _nc_free_and_exit - curses memory-leak checking


   #include <curses.h>

   void _nc_freeall(void);
   void _nc_free_and_exit(int);


   These  functions  are  used to simplify analysis of memory leaks in the
   ncurses library.   They  are  normally  not  available;  they  must  be
   configured  into  the  library  at build time using the --disable-leaks
   option.  That compiles-in code that frees memory  that  normally  would
   not be freed.

   Any implementation of curses must not free the memory associated with a
   screen, since (even after calling endwin), it must be available for use
   in  the next call to refresh.  There are also chunks of memory held for
   performance reasons.  That makes it hard to analyze curses applications
   for  memory  leaks.   To  work  around  this, one can build a debugging
   version of the ncurses library which frees those chunks which  it  can,
   and provides these functions to free all of the memory allocated by the
   ncurses library.

   The _nc_free_and_exit function is the preferred one since some  of  the
   memory  which  is freed may be required for the application to continue
   running.  Its parameter is the code to pass to the exit routine.


   These functions do not return a value.


   These functions are not part of the XSI interface.

Free Software

Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.
